Dual-head tool system with rotatable handle

Abstract

A dual headed tool having a rotatable arm has a shank with a tool head at each end. The shank slides through a rotatable hub positioned at the distal ends of the tools handle. One half of the shank is inserted into a longitudinal bore extending through the handle while the other half of the shank extends outward so that the tool head at its end may be used. The shank may be slid out of the bore within the handle and rotated to alternate which end of the shank is used. The tour may also be configured without the shank extending into the longitudinal bore in the handle, such that the handle extends away from the shank at an angle between 0° and 180°.

The invention claimed is: 
     
       1. A dual headed tool comprising:
 a handle having a longitudinal bore extending in a proximal direction from a distal end of the handle, and a fork end of a knuckle joint extending in a distal direction from the distal end of the handle; 
 a rotating hub forming an eye end and a pin of the knuckle joint and extending through the fork end of the knuckle joint, the rotating hub having an axis of rotation perpendicular to the longitudinal bore; 
 a through hole extending through the rotating hub and perpendicular to the axis of rotation of the rotating hub, the through hole being alignable with the longitudinal bore of the handle; 
 a key partially extending into the through hole; 
 a shank having a tool head at a first end and a tool head at a second end, the shank extending through and forming a cylindrical joint or prismatic joint with the through hole of the rotating hub; 
 a keyway extending along a side of the shank and defined by a first shoulder proximal to the first end of the shank and a second shoulder proximal to the second end of the shank; 
 wherein the shank is slidable into the longitudinal bore of the handle when the longitudinal bore of the handle and the through hole of the rotating hub are aligned, thereby forming a cylindrical or prismatic joint, and 
 wherein the rotating hub is rotatable such that the through hole therein may be positioned out of alignment with the longitudinal bore in order to position the shank at an angle with respect to the handle.
